I have this. I haven't had any issues with it. I have nothing to compare it to though. I wasted one putting it on but that was my fault. It does smudge up a lot, but again I have nothing to compare it to. That may be typical of most screen protectors. It's cheap and serves its purpose.
**edit: Pic of the product applied (from amazon-not my pic). Some people may not like the way the cutouts are. Doesn't really bother me.
